    I did try to warn you, I'll bet you'll still start salivating and giggling when you see the ppd figures though :)

    I'll get saving:duh:


    They quite low clocked though, so I'm wondering how one of those 16threads at 2ghz would compare to say an i7 8 thread at 4ghz.

    A couple of days ago - but it's taken longer to finish the review than expected. Now that's about 99 per cent done I reckon we'll put it live tomorrow.

    I've just looked at the headline fingures on the review. PPD is good, but electric consumption totally kills it.:wallbash:

    638W at idle, 1131W at load for 114958ppd Are those figures right??

    Compare that to the 2x5650 cpu set up.

    143W at idle, 336W at load for 62102ppd (was that idle wattage for a single cpu or dual?)

    Now compare it to THREE 2x5650 set ups.
    429W at idle, 1008W at load for 186306ppd Less energy used and three times the ppd.

    Folding wise the quad cpu set up is a poor investmant in terms of points per watts. It might give you the points but at what running cost financially.

    When's the SR-2 and 2x5650s over clocked review coming?:hehe:

    Yes, the power figures are definitely correct.

    Don't forget that in a 4P server such as Nehalem EX there is a lot of redundancy/management hardware that draws a lot of juice.

    As the review says, it's definitely not for everyone, particularly if you work can be distributed across multiple machines in a cluster.

    Did you fold a full bigadv unit when you did the reviews on the opterons and xeons?

    It might be worth posting in the folding @ home forum bigadv thread as this is the fastest bigadv folder on the planet. Currently the fastest one logged in the thread is a 4 socket Istanbul setup @ 13:08 minutes per 1% which is slower than the xeons.
